Can we have patients pay for unlisted code 92700 which we use for vestibular testing, VEMP (Vestibular-evoked myogenic potential) and HIT (Hit Impulse Test) and not file their insurance? This would include Medicare and commercial insurance. Medicare will sometimes pay this code and other times deny as not medically necessary or experimental. If we are in network are we obligated to file or can we have patient pay? I want to make sure we are doing the right thing. Thank you.
